Extreme Summit X670V STP disabled by default, it still will send BPDU package?

I just wanted to know if it still will send BPDU package when STP not enabled on Extreme Summit switch. From my understanding, it should not send BPDU message when STP not enabled. The background - As in our Production Env, we enabled BPDU guard on cisco Nexus 7K one Trunk port connected to a Summit X670V switch to root guard. However, a mistaken operation on the Summit switch by putting all port to a VLAN cause the Cisco switch received a large of BPDU package then put the port on the err-disabled status.
